ROCKING-CHAIR.

Specification of Letters Yatent.

Patented Dec. 6, 1921.

Application filed August 3, 1920. Serial No. 400,985.

To all whom it may concern:

Be it known that I, ANTON]: RUDNICKI, a citizen of Poland, residing atChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Rocking-Chairs, of which thefollowing is a specification.

This invention relates to certain new and useful improvements in rockingchairs and has for its primary object to provide a rocking chairembodying a bellows attachment whereby rocking movement of the chairwill create a current of air for circulation through passages in thechair frame and escaping from outlets in communication with the passagesand directed toward the occupant of the chair.

A further object of the invention aims to provide an air blowingattachment for rocking chairs wherein bellows elements are attached tothe chair and supporting frame with spring devices for causing the chairto assume a normally central position relative to its support, a furtherobject contemplating an adjustable foot rest for the occupant of thechair, the foot rest having guide means slidably associated with thechair beneath the seat portion thereof.

lVith the above general objects in view and others that will appear asthe nature of the invention is better understood, the same consists inthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicatecorresponding parts throughout the several views,

Figure 1 is a side elevational view of a rocking chair constructed inaccordance with the present invention, the adjustable foot rest beingshown projected in dotted line position.

Fig. 2 is a top plan view of the same showing the air exit openings inthe chair bottom and side arms,

Fig. 3 is a horizontal sectional view taken on line III-III of Fig. 1showing the bellows attachments and centering springs for the rockingchair,

Fig. 4 is a front elevational View of the chair, partially broken away,and

Fi 5 is a detail sectional view on line V\ of Fig. 4 showing the bellowsconstruction.

Referring more in detail to the accompanying drawings, there isillustrated a rocking chair mounted upon a base frame and having devicesassociated therewith for creating a current of air during the rockingmovement of the chair with air passages in the chair frame having exitopenings directed toward the seat portion of the chair, the base frameincluding a pair of side ars l mounted upon end feet 2, preferably ofcushioning material and having the upper faces thereof grooved orchanneled as 3 to provide guideways for the rockers of a chair.Transverse bars 4 connect the side bars 1 and hold the same in spacedrelations as clearly shown in Figs. 3 and 4.

The rocking chair comprises forward and rearward corner posts 5 and G ofany preferred design connected by the arm rests '7 adjacent their upperends and connected at their lower ends to the rocker feet 8, the lowerfaces of which are provided with cushioned treads 9 with the rockers andthe cushion treads extending into the upper grooved faces 3 of the framebars 1 clearly shown in Figs. 1, 2, and 4. A rectangular seat board 10is attached to the corner posts 5 and 6 while a back support 11 of anydesired curvature extends between the rear posts 6 as shown in Fig. 4.

Means is associated with the rocking chair and supporting frame forcreating a current of air through the rocking chair and embodies themounting of a platform 12 upon feet 13 supported on transverse bars 4 asshown in Figs. 1 and 4 and is held immovable relative to the base frame.A bellows 14 of the type clearly shown in Fig. 5 extends between theplatform 12 and the seat bottom 10 at the front and rear edges there of.Each bellows 14 has a controlling inlet valve 15 at the lower endthereof overlying a registering opening 12 in the platform 12 while theupper end of the bellows is provided with an unrestricted opening 14registering with an opening 10 in the bottom face of the chair bottom10, the chair bottom having an inner chamber 16 providing acirculatingair space with outlet openings 17 in the upper face of the chair bottom10 and arranged at desired points as shown in Fig. 2. The rear posts 6of the chair are provided with air passages 18 in communication with theair passage 16 in the chair bottom 10 with exit openings 18 for thepassages 18 adjacent the upper ends of the posts 6. To

provide for a normal central positioning of the rocking chair upon thebase frame bars 1, there is rovided a plurality of coil springs 19central y connected to the ring 20 at the underside of the chair bottom10 and radiating therefrom and anchored at their ends as at 21 to thecorners of the platform 12.

An adjustable foot rest embodies a foot board 22 carried by arms 23slidable in guides 24: carried by the opposite sides of the chair frameas shown in Fig. 4.

An occupant within the chair resting upon the seat 10 and back 11 mayhave his feet supported on the foot board 22 of the. extension frame.Rocking movement of the chair is assisted by the springs 19 connected tothe chair bottom and the stationary platform 12, such rocking movementcommunicating reciprocating motion to the bellows 1 1, alternatelyoperating to draw air through the openings 12' in the platform 12 by wayof the valve 15 and force the same through the opening 10 in the seat tothe air compartment 16, the current of air circulating therefrom andescaping through the Kill openings 17 in the chair bottom and throughthe exit openings 18 in the rear side posts of the chair. The rockers 8of the chair being mounted upon cushioned feet 9 and guided in thechannels 3 of the bars 1, an easy shock absorbing motion is provided forthe chair, the alternatelyoperating bellows providing a constant currentof air circulating through the chair frame and escaping through openings in the manner describe \Vhile there is herein shown and describedthe preferred embodiment of the present invention, it is nevertheless tobe understood that minor changes may be made therein without departingfrom the spirit and scope of the invention as claimed.

What is claimed as new is The combination with a rocking chair of amounting base therefor, a platform sup-V ported on the mounting-baseincluding for ward and rear upright standards and a rectangular plateupon said standards, an air bellows rigidly connected to the forward andrear ends of said plate in engagement with the chair bottom and springtension means anchored to the four corners of said plate and theunderneath center portion of said chair bottom for normally maintainingthe chair in a level position.

In testimony whereof I afiix my signature.

ANTONI RUDNIGKI.
